DOOR HANGER.

Application filed August 25, 1924. Serial No. 734,087.

To all whom it may concern:

Be it known that I, FRANK E. HOWARD, a citizen of the United States ofAmerica, and a resident of Hartford, Connecticut, have invented certainnew and useful Improvements in Door Hangers, of which the following is aspecification The principal object of my invention is to provide animproved door hanger of the .ype employing a combined'radial and thrustbearing for the sheave, which can be readily disassembled and assembled,and any worn part replaced by a new one, should such be required.

Another object is to so construct the hanger that the central or pinportion can be left soft for riveting, Whi 'e the outer and inner ballraces may be made as hard as desirable.

lVith these and other objects in View, which will become moreapparent asthe description proceeds, the invention resides in the construction,combination and arrangement of parts hereinafter more fully describedand claimed.

In the drawings,

Figure 1 represents a vertical sectional view taken transversely througha doorhanger, and associated parts, constructed in accordance with myinvention.

Figure 2 represents a sectional view taken on the line 2-42 of Figure 1.v

Figure 3 represcms a'view similar to Fig. 1, of another form of theinvention, parts of the mechanism being shown in elevation, and

Figure 4 represents a sectional view on the line 4-4 of Fig. 3.

Referring more particularly to the drawing, the door is indicated at 3,a fixed horizontal track above the to of the door, and on which thesheave of t 1e hanger rolls,,is indicated at 14, and one of the metalplates,

from which the door is suspended, is indicated at 4. A pin 5 is threadedfor the reception of a cylindrical bushing 6, the pin being preferablymade of metal sufficiently soft that its outer end 7 may be riveted, asindicated, to the plate 4. The pin 5 is provided with an integral flangeor collar 8, which abuts against the inner surface of the plate 4, andsuch flange forms a thrust hearing surface for one row of a double rowof bearing balls 9.

' The bushing 6 is turned up on the pin 5 and such bushing is made ofmetal as hard as desirable, since its outer cylindrical surface is tooperate as the inner race-way or inner radial bearing surface for thedouble row of bearing balls. The flange 10 integral with the bushing 6,forms a thrust bearing surface spaced from the flange 8, for the otherrow of balls.

Surrounding the bushing 6, and interposed between the flange 8 and theflange 10, is a the outer race-ways or outer radial bearing surface forthe rows of bearing balls. Similarly to the bushing 6, the sheave orroller is made of metal of the desired hardness.

In assembling the device the bushing is turned up on the pin 5 until thetwo rows of balls bear upon the inner Web 12 of the roller 11, and uponthe flanges 8 and 10 of pin 7 and bushing 6 respectively. The bushing isthen given a backward turn just sufiicient to free the balls and is setin this position either by the use of a locking pin or by prick punchingas described below.

The vertical pressure caused by the weight of the door is taken by thedouble row of balls, between the cylindrical outer surface of thebushing, and the inner cylindrical surfaces of the sheave. Anyhorizontal side pressure, produced by wind, or any other cause, pressesthe web 12 against the row of balls opposite to the direction from whichthe pressure comes, the balls in turn, pressing against either theflange 10 of the bushing or the flange or collar 8 of the pin, as thecase may be.

The outer end of the bushing 6 is provided with two or more slots orrecesses 15, and the bushing may be locked in position on the pin by theuse of a split pin 16 which is passed through two opposed slots, andthrough a hole in alignment therewith, drilled through the pin 5.Aportion of the usual housing in indicated at 17.-

, From the foregoing it will be observed that the sheave and associatedparts of the hanger may be readily disassembled by removing the spit pin16, and unscrewing the bushing, whereupon the sheave and the balls maybe readily removed. Any worn part of the hanger may be readily replaced,and the hanger again easily and quickly assembled, and all of thiswithout the use of any special tools.

In the structure shown in Figs. 3 and 4, the horizontal track 14 is madein two parts of the shape shown. The flange 10 on the bushing 6 islocated at the end of the bushing, rather than inwardly of the end as inFig. 1, and this flange is provided with the slots 15 into one or moreof which, in assembling the device in the manner above described, thethreads of the pin 5' are prick punched as indicated at 18. It will beunderstood that either of the methods described for locking the parts inassembled and adjusted position may be used in connection with eitherform of the invention.

The foregoing detailed description has been given for clearness ofunderstanding and no undue limitations should be deduced therefrom, butthe appended claims should be construed as broadly as permissible, inview of the prior art;

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a door-hanger, the combination of aplate, a threaded pin of relatively soft metal having one end rivetedthrough the plate, said in having an integral flange bearing againstsaid plate, n interiorly threaded bushing of relativel; hard metalthreaded on said pin, and adjacent its outer end being rovided with anintegral circumferential ange, the outer surface of said bushing betweenthe said flanges forming an inner ball race-way, a sheave of relativelyhard metal surrounding and spaced from said bushing, and interposedbetween the flange on said pin and the flange on said bushing, and beingprovided with an inwardly extending web, and a double row of ballsinterposed between the sheave and bushing and between the flange on thepin and the flange on the bushing, and being separated 'by and bearingagainst said web, said bushing at its outer end being provided withnotches, and a split pin extending through said notches and through analined opening in said pin.

2. In a door-hanger, the combination of a plate, a pin of relativelysoft metal having one end projecting through and riveted to said plate,said pin being provided with an integral flange bearing against saidplate, a bushing of relatively hard metal threaded on said pin andadjacent its outer end being provided with an integral flange spacedfrom the said flange on the pin, means for preventing accidental turningmovement of the bushing relatively to the pin, and a sheave surroundingthe bushing and inter posed between the flange thereon, and the flangeon the pin, and bearing balls interposed between the sheave and thebushing and the said two flanges.

3. In a door-hanger, the combination of a plate, a threaded pin rivetedat one end through said plate and having an integral flange bearingagainst said plate, a bushing turned on the pin and having acircumferential flange, a sheave surrounding the bushing and having aninwardly extending web, a row of balls on one side of the web andbearing against the bushing, the web, the sheave and the flange on thebushing, a row of balls on the other side of the web and bearing againstthe bushing, the Web, the sheave and the flange on the pin, and meansfor locking the bushing relatively to the pin.

4. In a door-hanger, the combination of a plate, a pin having one endriveted in said plate, and having an integral flange bearing againstsaid plate, a bushing threaded on the pin, and provided with an integralflange spaced from the first said flange, and a sheave and bearingstherefor, surrounding the bushing and interposed between the flangethereon and the flange on the pin.

5. In a door-hanger, the combination of a plate, a pin having one endsecured to the plate and having a flange adjacent to said plate, abushing threaded on the pin and having a flange spaced from the flangeon the, pin, a sheave surrounding the bushing and disposed between thesaid flanges and having an inwardly extending web, a row of balls on oneside of the web and bearing thereagainst and also bearing against the,bushing and the sheave and the said flange on the bushing, a row ofballs on the other side of the web and bearing thereagainst and alsobearing against the bushing and the sheave and the said flange on thepin, and means for locking the bushing relatively to the pin.

(3. In a door-hanger, the combination of a plate, a pin secured at oneend to the plate and at its other end being free and having a flangeadjacent to said plate, a bushing threaded on the pin and having aflange spaced from the flange on the pin, a sheave and bearingstherefor, surrounding the bushing and interposed between the flangethereon and the flan e on the pin, and means for locking the bus ingrelatively to the )in.

In testimony whereof'I hereunto a x my signature.
